2004 Kia Sorento wheel bearing

Why didn't you say if it's the front or rear? I'm guessing it's the front because they fail most often by making a buzzing noise. If it's the bolted-on style, an hour and a half is about typical. A lot of imports still use pressed-in bearings. Many of those require special tools and take longer, but the bearing costs less than the complete bolt-on assemblies.
